Description

Technical Field

[0001] This utility model belongs to the field of processing technology of isolation transformer protection boxes, and in particular relates to a hole-opening device for the lifting ring mounting hole on the top plate of an isolation transformer protection box. Background Technology

[0002] Isolation transformer protective boxes are typically rectangular or cubic in shape, and generally consist of side plates, top plates, bottom plates, and door plates. Lifting rings are usually installed on the top of the top plate. Holes are made at appropriate positions on the top of the top plate using a punching device, and then the lifting rings are installed through the holes to facilitate the hoisting and transportation of the isolation transformer.

[0003] Currently, the top of the isolation transformer protection box usually has mounting holes for lifting rings. When the punching equipment punches holes in the top plate, the top plate may shift during placement, which will cause the holes to shift. This shift in the top plate holes will cause the lifting rings to shift in position, which may pose a safety hazard to the hoisting of the isolation transformer protection box. Therefore, there is a need for a device for punching mounting holes for lifting rings on the top plate of the isolation transformer protection box. This device can use a positioning structure to help straighten the top plate and prevent the holes on the top plate from shifting due to uneven placement, thus ensuring the neatness of the holes on the top plate. Utility Model Content

[0004] The purpose of this utility model is to provide a hole-opening device for the lifting ring mounting hole on the top plate of an isolation transformer protection box. This device can assist in aligning the top plate through a positioning structure, preventing the openings on the top plate from shifting due to uneven placement, thus ensuring the neatness of the openings on the top plate and solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A hole-opening device for the mounting hole of the lifting ring on the top plate of an isolation transformer protective box, comprising a processing table set on the top of a punching machine, a slide rail set on the top of the processing table, a positioning plate fixedly connected to the front of the slide rail, and fixed frames fixedly connected to both sides of the processing table. A slide rod is fixedly connected to the inner cavity of the fixed frame, the slide rod passes through the slide rail and is slidably connected to the slide rail, and a threaded rod is rotatably connected to the inner cavity of the fixed frame, the threaded rod passes through the slide rail and is threadedly connected to the slide rail. A box is fixedly connected to the front of the processing table, and a rotating rod is rotatably connected to the inner cavity of the box. Two symmetrical bevel gears are fixedly connected to the surface of the rotating rod. The front of the threaded rod passes through the inner cavity of the box and is fixedly connected to a bevel gear. The bevel gears mesh with each other. The right end of the rotating rod passes through the outside of the box and is fixedly connected to a turntable.

[0006] Preferably, a support frame is fixedly connected to both sides of the inner cavity of the processing table, and a collection groove is provided on the top of the two support frames, with a handle fixedly connected to the front of the collection groove.

[0007] Preferably, the carriage is inverted U-shaped, the bottom of the positioning plate is attached to the top of the processing table, and the two ends of the carriage are respectively located in the inner cavities of two symmetrical fixed frames.

[0008] Preferably, the inner cavity of the box is fixedly connected with multiple longitudinal reinforcing plates, and the rotating rod passes through the reinforcing plates and is rotatably connected to the reinforcing plates.

[0009] Preferably, the front of the handle is cylindrical, and the surface of the handle is provided with anti-slip texture.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model rotates the turntable to make the rotating rod rotate. The rotating rod drives the threaded rod and the slide to move in a threaded motion through the first and second bevel gears. By limiting the sliding rod, the slide moves the positioning plate to a suitable position on the top of the processing table. This achieves the purpose of assisted alignment of the top plate through the positioning structure, avoiding the offset of the opening on the top plate due to uneven placement, and ensuring the neatness of the opening on the top plate.

[0012] 2. By setting up a collection trough, after the punching machine has punched the top plate, the sheet metal that falls off the punch will fall from the punch at the top of the processing table. At this time, the collection trough will collect the sheet metal, preventing the waste material falling from the punch of the top plate from scattering randomly and ensuring the cleanliness of the processing environment.

[0026] In summary, the hole-opening device for the lifting ring mounting hole on the top plate of the isolation transformer protection box works by rotating the turntable 12, which causes the rotating rod 9 to rotate. The rotating rod 9, through the first bevel gear 10 and the second bevel gear 11, drives the threaded rod 7 and the slide 3 to move in a threaded motion. Through the limiting of the slide rod 6, the slide 3 drives the positioning plate 4 to slide to a suitable position on the top of the processing table 2. This achieves the purpose of assisted alignment of the top plate through the positioning structure, preventing the opening on the top plate from shifting due to uneven placement, and ensuring the neatness of the opening on the top plate.
